This is the Redridge Dam, built in 1901 and used to provide water for a copper stamp mill. It is one of 3 steel dams built in the US and one of 2 still standing. With 308" of snow melting this spring it got to the highest point in years.

I'll bet a nickel that it's Wrought Iron, not Steel, since the inclusions are a mighty help against corrosion.

That said, steel's possible, since all the old viking swords and shit are found at river bottoms - the water is a low-oxygen environment, so as long as it stays wet, it won't rust much. Wet, then air, equals massive corrosion... generally speaking.

Just wondering, because stuff like that is what I do for a living.
Looks like a cool place.

I don't believe they are going to do any restoration on it. We are a small and pretty poor area so funding is very hard to get for a full resto. I would love to see the concrete redone or maybe a small hydro plant installed to make it functional again as a dam but I think that's a long shot.
